Definitions
- Document US-A-5 100 429 discloses a catheter comprising a body with two lumens, a balloon of a tight-transmitting material, a flexible light conductor, and a stent of a plastic material that cures due to the action of light, the balloon having a proximal section arranged on the distal end of the body and a distal section provided with a separate section to which the distal end of the light conductor is fixed.
- the catheter can be inserted into the patient and its balloon can be placed in the required position by introducing a stiff guide wire through the lumen, until the end of the guide wire is placed against the distal end of the balloon member, and stretches the latter in line with the basic body.
- a light conductor in particular an optic fibre bundle
- the end of this optic fibre bundle has been treated in such a manner that light, which is admitted into the proximal end of the fibre bundle, is emitted in a radial direction at the distal end situated inside the balloon. This can be achieved by providing the distal end of the light conductor with a somewhat roughened surface, for instance by means of grinding.
- This end-section can be made of solid light-conducting material, whereas the section extending from that end-section to the proximal end-section is made of an optic fibre bundle.
- a preferred embodiment is characterised in claim 2.
- the light conductor which straightens the balloon member and keeps it in line with the basic body.
- this embodiment ensures that the distal end of the light conductor is placed in the right position inside the balloon member, so that one can be certain that the light is supplied to the right place.
- a suitable embodiment is characterised in claim 4. If the stent itself is also visible under NMR-conditions and/or when using X-radiation, for instance by incorporating a suitable filler in the plastic material of which the stent has been made, the relative position of the working end of the light conductor in relation to the stent can be looked at and checked carefully in a catheterization laboratory.
- the assembly illustrated in figure 1 comprises a catheter 1 with a light conductor 10 received inside it.
- the haemostatic device 4 comprises in the usual manner a central channel which is connected with the lumen of the catheter connected to it. Through the connection 12, an elongated element, in this case a light conductor 10, can be introduced in a sealed manner. Via the connection 13 liquid or gas under pressure, for the purpose of expanding the balloon member 6, can be supplied.
- the blood vessel 20 is for instance locally impaired, and this impairment is to be reinforced by means of a stent 21.
- the stent 21 used has been made of a plastic material which cures due to the action of light, in particular UV-light.
- the stent 21 is introduced into the patient in compressed state, arranged around the balloon member 6.
- marking rings arranged on either side of the balloon member 6, the position of the balloon member and consequently that of the stent 21 can be visualized on for instance an X-ray screen.
- a stiff guide wire is for example used instead of the light conductor 10, which is positioned with its distal end against the relatively distal end 8 of the balloon member 6, so that the balloon member is stretched on introduction.
- the guide wire is replaced by the light conductor 10 and liquid under pressure is supplied via the connection 13 in the haemostatic device, as a result of which the balloon 6 and consequently the stent 21 will expand.
- the source of light 11 is activated and the stent exposed to the light emitted radially from the end 14 of the light conductor 10.
- the light source 11 is switched off and the pressure inside the balloon 6 drained off; as a result the balloon will contract and the catheter can be removed completely, leaving the expanded stent in situ.
- Figure 3 illustrates a portion of the aforementioned embodiment of the assembly according to the invention.
- the balloon 25 has been provided with a separate end-section 26 at its relatively distal end, in a depression of which the distal end 28 of a light conductor 27 has been fixed, for instance by glueing.
- the light conductor 27 thus forms a unit with the catheter and provides a certain bending stiffness at the balloon member 25, which enables the introduction of the catheter and in particular the balloon member thereof.
- the light conductor 27 is provided with two marking rings 29, which visualize the position of the balloon on for instance an X-ray screen.
- the light conductor 27 extends through the single lumen 30 of the basic body of the catheter and can be moved inside it.

Claims (5)
- An assembly of a catheter (1), a stent (21) and a light conductor (27), wherein
the catheter (1) comprises a tubular body (2) with a proximal and distal end (5) and provided with a single lumen (15) and a balloon member (6) made of a light-transmitting material, wherein
the stent is made of a plastic material that cures due to the action of light, and wherein
the light conductor (27) is flexible and rod-shaped and comprises light conducting material and has a smaller diameter than the lumen (15) of the body (2) and a length greater than the length of the catheter (1),
the balloon member having an end-section arranged on the distal end (5) of the body (2) and an opposite distal end-section (8) which is closed and is provided with a separate end section (26) with a depression in which the distal end (28) of the light conductor (27) is fixed. - An assembly as claimed in claim 1, wherein the light conductor (27) extends from the proximal end through the lumen (30) to the distal end (26) of the balloon member (6).
- An assembly as claimed in claim 1 or 2, wherein close to the opposite end-sections of the balloon member (6) marking elements (29) are arranged which are visible under NMR-conditions and/or when using X-radiation.
- An assembly as claimed in claim 3, wherein the marking elements (29) are arranged on the light conductor (27).
- An assembly as claimed in claim 1, wherein the separate end section (36) comprises a guiding lumen (37) extending from a tip to an opening (38) in a wall of the separate end section (36) close to the balloon member (6).
